https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-5.18.y2022-03-10T17:29:31ZRISC-V: Add arch functions for non-retentive suspend entry/exit2022-03-10T17:29:31ZAnup Patel2022-02-10T05:49:42Zurn:sha1:63b13e64a829e7b12fba81fccbea0d5448fc0c24
The hart registers and CSRs are not preserved in non-retentative
suspend state so we provide arch specific helper functions which
will save/restore hart context upon entry/exit to non-retentive
suspend state. These helper functions can be used by cpuidle
drivers for non-retentive suspend entry/exit.
